You've got some fair sailing ahead.
Blue Dragon: Is okay, it has no redeeming story, but the gameplay is very traditional. 8/10
Tales of Vesperia: Has only one redeeming quality. You can get together and play through story mode seamlessly with 3 other people. Not online, but it's a very fun and bonding experience.
Mass Effect: I s a good choice if you haven't played this gem of a game yet.
Fable 2: Is only good with DLC, otherwise it failed to live up to it's reputation.
That's it for worthy RPG's
Now for the other stuff
Infinite Undiscovery: Blech, not worth buying. Very bad game design, hidden-princess vanilla plot. Horrible Level design (A la Dark cloud 2) and bad voice acting. The game goes along waay to slowly, with zero pacing, and involves zero new ideas. Not fun.
Star Ocean: Is a bit of a doozy. It wasn't very good story-wise, but the game played well. just don't expect any of the characters to be deeper than baths you've taken.
